Considering "Performance" Parts (2010 JSW)

Hello,

I've have spent some time on these forums and the rest of the site. Lots of good info!

Some questions:

- What would you say about performance parts wearing on my clutch? Is it strong enough to handle most intake/exhaust bolt-on and chip combinations?

- My diesel experience is limited to John Deer so help me out on this one: adding performance parts (no-chips) would affect HP mostly or is torque boosted as well. I assume you would gain turbo efficiency more than anything. Assuming the stock computer would not add anymore fuel.

- Speaking of after-market chips: are they merely translators of the signals? I looked at a couple in-line ones. If it translates after the main computer that would invalidate all your fuel consumption statistics.

I'm kind of window shopping for some "bolt-on" parts that might give the car a little more HP. Torque is there for a wagon, which is to be expected from a diesel.

While its under warranty you would be better of getting the plug-in chip which does re-flash the ecu its been chipped. Rechipping increases power and torque. If its been re-flashed the service dept. will pick it up and void the warranty if thats caused the warranty fault.

I don't know what power you have as standard but I'm told if you go over 200bhp the clutch and transmission won't stand it. ;)

Manual or DSG?

From what I've heard, the clutch is fine. The DSG is power limited due to the transmission.

The tunes will increase hp and torque by adding fuel and boost.

The best tunes will overwrite the stock programming. Any dealer reflashes would overwrite it and they are detectable. The tuning boxes are plug in piggybacks and can be removed.

Manual.

To clarify my understanding: there are tuning boxes, re-flashing, and re-chipping ("plug-in chip which does re-flash the ecu its been chipped")? Or is re-chipping and tuning boxes synonymous?

So those piggybacks would invalidate your fuel consumption stats?

How are they controlling boost? Some bypass that regulates the boost I would guess.

I would think tuning and/or parts would lower your economy due to "enjoying the extra power", but generally do they hold up to the advertising of increased economy?

I don't know about the piggybacks changing mpg stats but I don't think so. I can only speak for myself - I've always had lower economy after mods.

A chip is the same as a flash. In ye old days, you actually soldered in a chip. Today you just overwrite the old programming. This is why a dealer update to the software will overwrite any aftermarket "chips". A tuning box is a physical box that plugs into the wire harness and they fool some sensors. I'm not sure exactly which ones.

You can tell the dealer not to flash it when they bring it in for maintenance but then they know it's chipped. I think revo works with dealers to keep the factory warranty if you do it thorough a dealer but you pay a premium for that.

Roger that.

Sounds like I might be in the market for hardware first.

I like my MPG :)

Anyone else chipped here? I have see some companies claim that their flashes keep the flash count to 0 so that your dealer wouldn't know (although if the dealer reflashes you're going to be losing out on the modification in the first place). Most seem to bring the specs up to the EU's GTD. I'd love to hear some feedback from people who actually have it done.
